I mportant User Information
Solid-state equipment has operational characteristics differing from those of electromechanical
equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://www.rockwellautomation.com/literature/) describes some important differences between
solid-state equipment and hard-wired electromechanical devices. Because of this difference, and also
because of the wide variety of uses for solid-state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.

Intertek certifies that this equipment has been found to comply with the
Essential Health and Safety Requirements relating to the design and
construction of Category 3 equipment intended for use in Zone 2 potentially
explosive atmospheres, given in Annex II to this Directive. The examination and
test results are recorded in confidential report No.100014190DAL-001.
Compliance with the Essential Health and Safety Requirements has been
assured by compliance with EN 60079-15.
WARNING: This equipment must be installed in an enclosure
providing at least IP54 protection when applied in Zone 2
environments.
Provision shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40% when applied in
Zone 2 environments.

Rockwell Automation Publication 1768-IN007B-EN-P - August 2010
Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage Category II
applications (as defined in IEC 60664-1), at altitudes up to 2000 m
(6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR 11. Without appropriate precautions, there
may be difficulties with electromagnetic compatibility in residential
and other environments due to conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be
mounted within an enclosure that is suitably designed for those
specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from
accessibility to live parts. The enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or
equivalent) if non-metallic. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain
product safety certifications.
In addition to this publication, see:
•Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1, for additional installation
requirements.
•NEMA Standard 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different
types of enclosure.

discharge, which can cause internal damage and affect normal
operation. Follow these guidelines when you handle this
equipment:
•Touch a grounded object to discharge potential static.
•Wear an approved grounding wriststrap.
•Do not touch connectors or pins on component boards.
•Do not touch circuit components inside the equipment.
•If available, use a static-safe workstation.

•35 x 15 mm (EN 50 022 - 35 x 15)
Screws M4 or #8 panhead screws
ATTENTION: This product is grounded through the DIN rail to
chassis ground. Use zinc-plated yellow-chromate steel DIN rail to
assure proper grounding. The use of other DIN rail materials (for
example, aluminum or plastic) that can corrode, oxidize, or are
poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm
(7.87 in.) and use end-anchors appropriately.

If You Are Using Screws to Mount Your Modules
The steps in these instructions show how to mount the modules on DIN rail.
If you are using screws instead of DIN rail, make these changes to the
instructions.
1. Follow the steps in Mount the Controller on the DIN Rail on page 10 to
connect the modules together.
2. Use the modules as a template and mark pilot holes on your panel.
3. Drill the pilot holes for M4 or #8 screws.
4. Use M4 or #8 screws to mount the modules to your panel. Use 1.16
N•m (10 lb•in) of torque.
5. Ground the module on a ground bus with a dedicated earth ground
stake.
6. Connect the ground bus to a functional earth ground on the DIN rail or
panel.
7. Refer to Industrial Automation Wiring and Grounding Guidelines,
publication 1770-4.1, for additional information.
IMPORTANT Do not use screws and DIN rail to mount the modules. It is
possible to break the mounting tabs off if you screw the modules
to the panel while they are on DIN rail

Connect the Module
Attach the RJ45 connector to the Ethernet port on the bottom of the module.
WARNING: If you connect or disconnect the cable with power
applied to this module or any device on the network, an electrical
arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
IMPORTANT
We recommend connecting the module to the network via a
100 MB Ethernet switch, which will reduce collisions and lost
packets and increase network bandwidth. For detailed
EtherNet/IP connection information, see the EtherNet/IP
Modules in Logix5000 Control Systems User Manual, publication
